Linear nevi, hemihypertrophy, connective tissue hamartomas, and unusual neoplasms in children

The association of cutaneous nevi, hemihypertrophy, and connective tissue overgrowth has been described in many patients. We report long-term follow-up in two boys with such association who in addition developed testicular neoplasms. One patient also had progressive spinal cord compression as a result of stenosis of the spinal canal, and required amputation of a severely deformed limb. The importance of careful, long-term management in such patients is emphasized.
